For one night the Santa Clara County Open Space Authority will extend operating hours at Rancho Cañada del Oro Open Space Preserve to give bicyclists a chance to experience the preserve after dark. This is a bicycle-only event. The preserve will be closed to all other users after sunset.

This special activity is limited to adults. No minors will be allowed, even if accompanied by an adult. Preserve parking is open to the first 50 vehicles to arrive at the staging area. Safety equipment is required (helmet, headlamp and bike lamp); a rear light is recommended. Participants will be required to register on-site and attend a short briefing before their ride. Registration will be held only the day of the event from 6:30 to 9 p.m. in the Casa Loma Road parking lot.

The Rancho Canada del Oro Open Space Preserve in western Santa Clara County along the foothills of the Santa Cruz Mountains offers 8 miles of trails for mountain bikers, along with hikers and equestrians during normal hours. No pets, no fires, no smoking at this park. No water is available so bring your own. Bikes are not permitted on connector trails into the adjoining Calero County Park. Access is via the open space parking lot beyond Bailey Avenue and McKean Road; go south on McKean, then west on Casa Loma Road about 2 miles to the OSA parking lot.
